Abstract: A control circuit for a frame memory includes a divider, a frame memory, a read control circuit, and a write control circuit. The divider divides image data into subfield data according to a plurality of subfields, where the image data is provided in synchronization with a first synchronization signal and in a unit of a frame. The frame memory has a plurality of blocks to store the subfield data. The read control circuit sequentially reads the subfield data from the blocks in synchronization with a second synchronization signal. The write control circuit writes new data to a first block before data written in a second block is read, and after data written in the first block is read by the read control circuit. The second synchronization signal may have a same cycle as the first synchronization signal and may be delayed by a preset delay time.
